To all whom t may concern.:

Be it known that l, Josemi il. lvianrorri, a citizen of the United States, residing vat Chicago, in the county oi Cool; and Stateot Illinois, haveV invented certain new and use ful Improvements in Safe-Door Construo` tions, of which the following is a specification,

This invention pertains to door operating mechanism and more particularly to a mechanism for .simultaneously operating double doors of safes and the like.

Hereto'fore, safes `and the like havebeen provided with double doors oi substantially the same sizeV adapted to engage one another tightly when in a closed position. Both doors in this construction are independently operable, that is to say, either door might be opened and closed without movement of the other door, but for some purposes, such as for altar saies, where it is desired to retain aesthetic features, and for other purposes where the mechanical features alone are most important, it isl desirableV to have both doors open sirnnltaneously.

It is therefore a primary object of my invention to provide a simple and inexpensive, but efcient and reliable mechanism vfor simultaneously opening both doors of a safe or other structure.

Another object is to provide a mechanism for simultaneously opening double doors oi safes of such nature and so constructed that the sa'fe doors may be readily opened by pulling upon the key, knob, or other projection provided., and wherein only one such means providing a hand hold may serve to open both doors.

Other objects and novelties of my invention will appear from the description and claims and from the drawing in which:

Fig. l is a Yfront elevationof a sate. con- .struction showing one form el" my invention applied thereto and,

Figs. 2 and 3 are plan, views et the meclranism taken along the line lll-ll ot Fig. 1.

'.lhe saire consists oi suitable irame niembers 2, 3, el, and 5, `forming the body and a pair oi doors (3 and 7 respectively pivotcd or hinged at 8, 9, 10, and 11 in the iframe members 3 and 5, although they may be otherwise hinged or pivoted in the framek members Q3 and 4 in any suitable manner as will be obviona The doors adapted tov engage in `slightly overlapping relation alongi aline substantially midway between the :trame members 2 and i as shown at 12.

rlhe hinge members 8 and 10v are preferably made slightly longer than the oppo site hinges of their respective doors and are journaled or hinged in the frame at 13 and lll. provided into which the hinge members -8 and project in order to provide operating room for cam members 16 and- 17 and a connecting toggle bar 18 extending between the cam members. Y

Each cam membcrfis provided with a slot v19 extending substantially `half-way through it, oi width to,` permit ready pas- .sage oit the ltoggle bar 18 therein, with a pivot pin 2O adapted to pivotally secure the end vot thetoggle bar 18 and a set screw 21 ior securing it to the hinge members 8 and 10. Thecam members 16 are preierably secured on the hinge pins to dispose the pivot pins 2O on opposite sides ot a plane passing through the axes of the two bottom hinges;V or,inv other words, the pivot A compartment or space isV pins are so disposed with respect to one another that planes passing through the axes of each hinge and its respective pivots will be angularly unsymmetrical or angulai-ly displaced, one from another. This construction is clearly illustrated Figs.

i 2 and 3.

Fig. 2 shows the mechanism'as it is preierably arranged when the doors are in closed position as indicated in dotted lines, while Fig. 3 shows the mechanism as it would appear when the doors are open. It is believed that the operation of the mechanism will be readily apparent 'from the foregoing.

I claim: i

1. In, combination, a pair of satte doors cooperatively engageable at one vertical edge `when in closed position, upper and centers of the door hinges when the doors are in` one ot their t-wo extreme positions and said shoulders, pins and bar being constructed and arranged so that opening and closing movements of one door will correspondingly open and close the other door and so that opening movements oit the doors beyond a predetermined position will be lin ited Vby engagement ot one et' said shoulders with the adjacent end ofthe bar.

2. ln combination, a pair of parallel spaced door frame members, a pair oi' sate doors cooperativeljT engageable at one vertical edge when in closed position, upper and lower hinges adjacent the opposite vertical edge ot each door and pivoted in said trame members, a cam member secured to each lower hinge between the lower edge ot' its door and the adjacent trame member, a shoulder on each cam member projecting generally in the direction o't the anis ot the adjacent hinge and on both sides ot' said hinge along a diameter thereof, a pivot pin on each cam member adjacent the shoulder thereon and a rigid bar pivoted to said pivot pins at its ends, said pins being so located on said members as to lie on substantiallj7 opposite sides of the line ot centers ot the door hinges when the doo-rs are in one of their two extreme positions and said cam meinbers, pivot pins and bar being constructed and arranged so that opening movements of the doors beyond ,a predetermined position will be limited byvengagement of one of said shoulders with the adjacent end of the bar.

3. In combina-tion, a-Ipair of sate doors each pivotally hinged at one vertical edge and cooperative at its other vertical edge with the corresponding` vertical edge ot the other door when said doors are in closed position,` a hinge member secured to each door and project-ing from corresponding horizontal edges of the doors in substantial alignment and substantially coincident with the pivotal axes o't the doors, a collar adjustably secured on each member for swinging movements therewith, a pivot pin on each collar eccentric of the axis of the member to which the collar is attached, a shoulder' on each collar adjacent the pin thereon and on a projection of a diameter ot the hinged member, and a rigid bar pivotally connected to said pins at its ends, said, pins being so located on said members as to lie on substantially opposite sides ot the line ot centers of the door hinges when the doors are in one ol their two extreme posit-ions and said pins being so relativelj7 positioned with respect to one another and to the axes of' said members that opening or closing increments ot one door will open or close the other door simultaneously and said shoulders each adapted to en gage one side ot' an end ot the bar to limit the extent of opening movement ot the doors.
